Edubuntu , previously known as Ubuntu Education Edition , is an official derivative of the Ubuntu operating system designed for use in classrooms inside schools , homes and communities .
25-885: Edubuntu is developed in collaboration with teachers and technologists in several countries. Edubuntu is built on top of the Ubuntu base, incorporates the LTSP thin client architecture and several education-specific applications, and is aimed at users aged 6 to 18. It was designed for easy installation and ongoing system maintenance. Included with Edubuntu is the Linux Terminal Server Project and many applications relevant to education including GCompris , KDE Education Suite , Sabayon Profile Manager, Pessulus Lockdown Editor, Edubuntu Menueditor, LibreOffice , Gnome Nanny and iTALC . Edubuntu CDs were previously available free of charge through their Shipit service; since version 8.10 (2008) it
50-469: A CD with free software for Windows/Mac and, finally, MILLE-Xterm itself. The MILLE-Xterm project's goal was to provide a scalable infrastructure for massive X-Terminal deployment. MILLE means Modèle d'Infrastructure Logiciel Libre en Éducation (Free Software Infrastructure Model for Education) and is targeted at educational institutions. As of 2009, MILLE-Xterm was integrated back into the LTSP as LTSP-cluster,
75-402: A CD. The primary goal of Edubuntu was to enable an educator with limited technical knowledge and skills to set up a computer lab or an online learning environment in an hour or less and then effectively administer that environment. The principal design goals of Edubuntu were centralized management of configuration, users and processes, together with facilities for working collaboratively in
100-459: A central location. In LTSP-cluster high-availability and high-performance thin-clients are specified through the optional use of redundant components. Services that can be load-balanced and made highly available are: LTSP-Cluster can support Linux application servers as well as Windows application servers and provides a similar level of support, centralized management, high-availability, and load-balancing features for both platforms. Also included

150-507: A classroom setting. Equally important was the gathering together of the best available free software and digital materials for education. According to a statement of goals on the official Edubuntu website: "Our aim is to put together a system that contains all the best free software available in education and make it easy to install and maintain." It also aimed to allow low-income environments to maximize utilisation of their available (older) equipment. The first Edubuntu release coincided with
175-496: A full desktop OS. Even a relatively slow CPU with as little as 128 MB of RAM can deliver excellent performance as a thin client. In addition, the use of centralized computing resources means that more performance can be gained for less money through upgrades to a single server rather than across a fleet of computers. By converting existing computers into thin clients, an educational institution can also gain more control over how their students are using computing resources as all of

This technology is useful in schools as it allows the school to provide pupils access to computers without purchasing or upgrading expensive desktop machines. Improving access to computers becomes less costly as thin client machines can be older computers that are no longer suitable for running
225-433: A portal (based on uportal), an open-source middleware stack, a CD with free software for Windows/Mac and, finally, MILLE-Xterm itself. The MILLE-Xterm project's goal was to provide a scalable infrastructure for massive X-Terminal deployment. MILLE means Modèle d'Infrastructure Logiciel Libre en Éducation (Free Software Infrastructure Model for Education) and is targeted at educational institutions. As of 2009, MILLE-Xterm
250-441: A project specializing in the large scale deployment of LTSP. One of the main differences between LTSP and LTSP-cluster is the integration of a web-based central control center that replaces the traditional "one configuration file per thin client" as is the method of client customization through LTSP's lts.conf file in the main LTSP. LTSP-cluster allows organizations to centrally manage thousands of thin clients and their parameters from

#1732891508277300-426: Is a free and open-source terminal server for Linux that allows many people to simultaneously use the same computer. Applications run on the server with a terminal known as a thin client (also known as an X terminal ) handling input and output. Generally, terminals are low-powered, lack a hard disk and are quieter and more reliable than desktop computers because they do not have any moving parts. This technology
325-404: Is also installable via a selection of "edubuntu" packages for all distributions using the official Ubuntu repositories ( Ubuntu and Kubuntu mainly). Since 14.04, Edubuntu became LTS -only; Edubuntu announced that they would skip the 16.04 LTS update and that they planned on staying with 14.04 due to lack of contributors. It would then be discontinued for a number of years, but as of April 2023,
350-536: Is only available as a download in a DVD format . In 23.04, Edubuntu's default GUI is GNOME . From 12.04 to 14.04, Edubuntu's default GUI was Unity ; however GNOME , which had previously been the default, was also available. Since release 7.10, KDE is also available as Edubuntu KDE. In 2010, Edubuntu and the Qimo 4 Kids project were working on providing Qimo within Edubuntu, but this was not done as it would not have fit on
375-424: Is support for virtual desktops for remote users using NX technology . The NX protocol can allow remote Windows and Linux sessions to be accessed from a web browser with very low bandwidth (40 kbit/s) requirements and tolerance for high-latency connections. The NX client runs on various operating systems including Linux, Mac, and Windows. LTSP v5.x added support for a thin client type known as "fat clients". With

425-507: Is used on the fat clients, which provides a few benefits. LTSP is unique in offering the ability for a computer to mount its root filesystem over a network and run applications locally. On the Windows platform, the closest equivalent solution is to use a technology like Intel vPro to run a client-side hypervisor and mount the root filesystem image using iSCSI .

475-459: The advent of inexpensive, relatively powerful computer hardware, the idea to run applications locally on the thin client while offering the manageability of a thin client solution became a reality. In the case of a LTSP fat client, the root filesystem is not a rudimentary chroot but a full Linux installation as a chroot. The fat client uses LDM to authenticate to the LTSP server and mounts user home directories using SSH and FUSE . The local CPU and RAM

#1732891508277550-400: The release of Ubuntu 5.10, which was codenamed Breezy Badger on 2005-10-13. With the 8.04 Hardy Heron release of Edubuntu it was given the name of Ubuntu Education Edition and was changed to be an add-on to a standard Ubuntu installation instead of being an installable Live CD . From version 9.10 onwards, Edubuntu changed to be available as a full system DVD instead of an Add-on CD. Edubuntu
